Segmented Defense Structure with Cell Fillers

Solution Overview

Problem

Current defense structures, such as reinforced concrete bunkers, are prone to widespread damage from shelling or missile attacks, leading to increased material consumption and weight, and lack effective measures to localize collapse and prevent fire risks.

Innovation Solution

A defense structure featuring a hollow structure with partitioned cells arranged in a three-dimensional pattern, filled with nonflammable fibers or fluids, and reinforced with stiffeners, which reduces weight while maintaining rigidity and strength, delays crack development, and suppresses penetration and fire risks.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the thickness of the bunkers or protection structures is increased to prevent damage spread, then the reliability is improved, but the weight and material consumption increase

Engineering Contradiction:

Improvedamage resistanceVSAvoidbunker weight

Core Design Contradiction:

ReliabilityVSWeight of stationary object

Solution Approach 1:

The bunker structure is divided into multiple cells by partition walls, creating a segmented configuration. This segmentation allows the structure to maintain reliability through distributed strength while reducing overall material consumption and weight compared to a solid monolithic structure of equivalent protective capability.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The invention uses composite construction combining partition walls, slabs, and fillers (such as earth or other materials) to create a multi-material system. This composite approach achieves enhanced protective reliability while optimizing material usage and reducing weight compared to homogeneous thick structures.

Inventive Principle:

Principle #40Composite materials
